WHAT IT DOES

What read_image does on AWS

AI agents call read_image to retrieve information from AWS without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why read_image is rated Low

The tool name 'read_image' suggests a retrieval operation on image data. Without a description, confidence is moderate, but the verb 'read' and lack of any write/delete/execute indicators point to a Read category. Severity is low as image retrieval typically has minimal blast radius unless sensitive images are exposed.

From the tool's definition Tool name 'read_image' indicates data retrieval with 'read' operation. No side effects suggested by the name.

RECOMMENDED RULE

The rule that runs read_image safely

PolicyLayer is an MCP gateway: it sits between your AI agents and AWS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For read_image, this is the rule to start with:

read_image Allowed

read_image is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "read_image": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect AWS, apply this rule, and every read_image call is checked against it from then on.
